The history of chip and PIN in the UK
The function of the chip in the card
How small businesses can utilize a chip and PIN card reader
It may seem quite commonplace todays, but the first chip and PIN solution that was ever widely used was available only in France. It used the French B0 standard and could only be used within domestic markets.
Before then, the world’s first multi-function chip card, which was developed by Visa, was used in Japan. Known as the SuperSmart card, it did not take off.
It was not until 2003 that the UK ran chip and PIN trials within its cards. Issuers took part in trials in Northampton and Dunfermline wit 117,000 cards being issued to locals.
To cope with the then new technology, over 500 chip and PIN card readers were installed locally and 14 cash machines were converted to adapt. The trail was a success and eventually led to a change in how payments were processed in the UK marketplace.
In 2006, the UK government decided that the enhanced security offered by chip technology, which forced card users to enter a four-digit personal identification number when they made a transaction, was worth making and the project was rolled out nationwide.
Cards had been used widely before then, all but replacing cheques as a means of not having to carry cash around, but transactions still had to be signed for.
The conversion to a chip and PIN reader in nearly all stores in the country, let alone the changes to credit and debit cards, meant that this was the largest consumer changeover since the country had adopted decimalised currency.

Although the presence of a chip in a debit or credit card is obvious – it can be seen housed within the plastic of the card – few people actually have a good understanding of how this small device functions.
The chip itself is known as an EMV, which is a term coined after the three giants in the industry who first agreed upon a common standard. They were Europay, MasterCard and Visa.
Today, the standard is managed by an independent organisation, named EMVCo, a consortium which includes other major card issuers.
The data held on a card is contained within the chip itself, making it more secure than on the magnetic strip on the back of the card. When a card is inserted into a chip and PIN card reader, it will offer up this data from its integrated circuits.
Essentially, the data held on the chip is the card number, its expiration date and so on, but a card machine is required to then ask the card issuer whether funds can be released for a transaction.
Crucially, the PIN number associated with the card is also stored, but this is something the vendor has no access to.
Buyers can review the sale and authorise the payment by entering their PIN into the vendor's chip and PIN machine. The system is only secure if the card owner keeps their PIN number secret.
Since it was rolled out, the humble chip and PIN card reader has worked its way into many corners of life. Once they were only found in banks, for cash machine transactions, and larger stores.
However, todaymany modestly-sized retailers and sole traders rely on them as a convenient means of taking payments.
Indeed, they have become essential business tools, so much so that the public has become accustomed to not carrying cash around, secure in the knowledge that their PIN number protects them from others accessing their available credit or bank balance.
Today, a mobile chip and PIN machine can be used just about anywhere, thanks to SumUp. All that is needed is a small reader and access to the internet via a smartphone or tablet.
Customers can now pay a vendor anywhere they like, even from their own home, making a small card reader an ultra-convenient tool for tradesmen and salesmen who travel frequently.
Along with the enhanced fraud protection that entering a PIN offers over the older signature method, UK inhabitants enjoy further consumer rights with cards that are fitted with EMV technology.
From 2009, the Financial Services Authority has placed the responsibility on banks and other card issuers to prove transactions are genuine, rather than consumers having to prove they were not if something goes wrong.
As such, the principle is that liability for errors has unquestionably been shifted to the card issuers. The status of cardholders has never been higher.
Since the adoption of chip and PIN card readers in the UK, security for cardholders has drastically improved. Not only are these readers found in large stores and banks, but they are now found throughout small pop-up shops, restaurants and with sole traders. The size and convenience of these card readers allow for alternative and secure payment methods.
